This study aims to investigate the impact of depth of field differences between the use of the 3D imaging system (NGENUITY® 3D Visualization System, Alcon, TX, USA) and conventional optical microscope in cataract surgery for highly myopic patients on intraoperative parameters and outcomes.
HM, which can dramatically cripple the eyesight of those affected, is a rampant ophthalmic disorder around the globe. It is in recent years that substantial studies covering the relationship between distinct variations and HM susceptibility sprang expeditiously. However, these studies have not yielded sufficiently credible and universally significant conclusions. Consequently, the study is conducted by including HM subjects residing in Northern China to explicitly illustrate this issue.
The study aims to observe the long-term changes of ocular（especially fundus） structure and visual function in patients with high myopia, so as to provide evidence for the prevention, diagnosis and prognosis of high myopia.
The purpose of this clinical study is to confirm the effectiveness and safety of low-level monochromatic red-light for high myopia control in adults
Currently, whether and when intraocular pressure (IOP) lowering medication should be used in progressive high myopia (HM) to control axial elongation is still a dilemma. Randomized trials are required to evaluate whether IOP lowering influences the growth of axial length in progressive HM eyes.
To screen and identify sensitive biomarkers for high myopia via a robust, convenient, and cost-effective approach according to the association between high myopia and concentration of biomarkers in tear fluid, saliva and blood among adults and children.
The purpose of this clinical trial is to investigate the incidence and magnitude of axial length shortening after repeated low-level red-light therapy in high myopia children and teenagers.
The study aimed to collect multi-factor information on school-age children with pre-clinical myopia, and to identify the initial factors and warning signs of myopia.
This is a prospective, multi-center, randomized comparative study. The purpose of the study is to evaluate and compare the postoperative visual outcomes and quality of vision of two diffractive trifocal intraocular lenses (IOLs) in patients with high myopic cataracts.
